Study on Information Retrieval Sorting Algorithm in Network-based Manufacturing Environment

The core problem of information retrieval is concentrated in the document for the user to retrieve the most relevant sub-set of documents, relying on sorting algorithms on the search results according to relevance sort, sorted the results as the user asked the query response information retrieval performance is determined by many factors, such as to query expressions quality index stemmer nonsense word disabled, query expansion technology, but fundamentally it is determined by the sort function sort function in some Standards document query indicates the degree of matching with the user, and accordingly to make a document with respect to the user's judgment, then the document in accordance with the degree of correlation with respect to the user in descending order, and returns the ordered list of documents as a result of the retrieval the pros and cons of the sorting algorithm directly affect the efficiency of the retrieval.
